1 Claim. l

The invention relates to a jar wrench, and more especially to a jarwrench Aand holder.

The primary object of the invention is the provision of an implement ofthis character, wherein the screw cover or cap and the body of the jarcan be firmly and securely held, so that the said cover or cap can beconveniently removed, and also the jar held during the removal of suchcap or cover, the clamping of the latter being effected in a unique andnovel manner. 2

Another object of the invention is the provision of .an implement ofthis character, Wherein there can be no damage to the jar while removingthe cover or cap therefrom, and the latter may be removed with dispatchand ease, or such cover or cap can be tightened on the said jaroptionally with the user of the implement.

A further object of the invention is the provision of an implement ofthis character, wherein it can be applied and removed without trouble,and when applied embraces both the cover or cap and the jar, so thatthese can be conveniently held during the working of the implement,there being separate operating members for the cover or cap and the jar,which are hand controlled.

A still further object of the invention is the provision of an implementof this character, wherein the clamping of the cover or cap and the jarare independent of each other, and are similarly regulated.

A still further object of the invention is the provision of an implementof this character, which is simple in construction, thoroughly reliableand eiiicient in operation, readily and easily applied and removed,strong, durable, conveniently actuated, without excessive exertion onthe part of a user, assuring against injury through breaking of the jar,and inexpensive to manufacture.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which show the preferred embodiment of the invention, landpointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a' top plan view of the implement constructed in accordancewith the invention and applied to a jar.

Figure 2 is a side view thereof, in an applied position.

Figure 3 is a side view of the implement removed irom the jar.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3 lookingin the direction of the arrows.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail A designates generally a portion ofa jar of the fruit or vegetable containing type, having a screw threadedcover or cap I0, while B denotes generally the implement constitutingthe present invention, and is in the form of a jar wrench and holder, aswill be hereinafter fully described.

The implement B comprises a split expansble and contractible jar-bodyembracing band II, and split expansible and contractible cover or capembracing band I2, which is smaller in diameter than the said band IIdue to the size of the cover or cap I0. The split areas of the bands IIand I2 are arranged on reverse sides of the implement B in its entirety.

The band I2 opposite the split therein has built thereon at itslowermost edge a curved laterally extending and depending ear I3, whilethe band I I similarly has built thereon opposite its split area anupstanding ear I4 at its uppermost edge, these ears I3 and I4, beingfitted with pivot connections I5 for the toggle link heads I6 of upperand lower pairs of operating levers I 6' and I 1, respectively. Thelevers with the head formations are of substantially T-shape.

The link heads I6 of the respective pairs of levers I6 and I'I arepivotally connected at I8 to the ends adjacent thereto of the bands IIand I2, one each of these ends I9 of the latter are outwardly offset toclear the other end next thereto, for the proper expansion andcontraction of each band without interference of its ends at the splitarea.

The band I2 at its top edge carries inturned rest ears or lugs 20 forcontacting with the top portion of the cover or cap I0.

The bands II and I2 at their inner faces are fitted with resilientlinings 2|, so as to avoid damaging the jar or cap in the use of theimplement B.

In the use of the implement B the same is applied as best shown inFigures 1 and 2 of the drawings. The clamping of the jar and cover orcap is effected by actuating the pairs of levers I6' and I'I,respectively. The ears I3 and I4 are provided with stops 22 to limit thethrow of the levers IB' and Il, when actuated. The bands II and I2 whencontracted rmly and securely clamp lthe jar and cover or cap, while theexpansion of these bands releases the same.

The pair of levers I'I is gripped in the right hand, which contracts thecap engaging member I2, so that it securely grips the cap. At the sametime, the pair of levers I6 is gripped in the left hand, which contractsthe jar engaging member I I, so that it securely grips the jar. Then theright .hand vwith levers I'I lis raised, While at the same time the lefthand With levers EG is lowered. Through this motion, levers I7 force theright side of cap engaging member away from the operator, and levers I6Kforce the -left side of the cap engaging member toward the operator,thus causing the cap engaging member, with cap, to rotate in acounterclockWisedi-rection. If the hands are moved in the oppositedirection, the cap will be turned in af'clookWise direction. The ears I3and lil, and the link heads +5, where they -connect to :the ears, arebent at a slightly different -ang-1'e,asfshown in `Figure 1,-so :thatthe capengaging member'can rotate freely Withoutrany binding.-IA-t'fis'only intended that the cap engaging member .move a shortdistance sufficient to 4loosen :a tight cap, -or -to tighten aloose'cap.

From the foregoing it is thought that `the `construction rand mannerofoperation of the :im- :plement -fwill .be clearly understood, andtherefore a more extended explanation has been omitted for the sake ofbrevity.

`What: isY claimed 4is:

An *implement 4of the kind described, 'compris- 'ingavsplitjar-body'einbraciiig band, "a split jar cap v'einbfra'cing band:parallel to and positioned fabo've said-bodyembracing band, ascurvedlaterally extending and depending ear on said cap embracing band at thecenter thereof opposite to the split ends thereof, an upstanding ear 0nsaid body embracing band at the center thereof opposite to the splitends thereof, the ears on said bands being positioned in opposedrelation to each other, a plurality of handles separated into pairs andhaving T-shaped heads on one end thereof, one end lof the heads of onepair being pivotallyfconnected tothe ear on'sa'id body embracing band,one end lofthe heads vof the other pair being pivotally connected to theear on said embracing band, the other ends of the T-heads pivotedfontheear on the cap embracing band 1being pivoted to the split endsrespectively of thebod'y embracing band, the other ends of the T- .headspivoted. on the ear on the body embracing band'being'pivoted to thesplit ends respectively of the cap embracing band, said handles beingadapted to be grasped in pairs and moved towardveach other to .cause atorque couple to be applied vtothe 'jar and cap 'to cause the cap'andjarpto be Inovedsligh-tly iniopposite directions to loosen the cap'fromthe jar.
